=head1 NAME

Sport::Analytics::NHL::Test - Utilities to test NHL reports data.

=head1 SYNOPSYS

Utilities to test NHL report data

 These are utilities that test and validate the data contained in the NHL reports to detect errors. They are also used to test and validate the permutations that are performed by this software on the data.
 Ideally, that method should extend Test::More, but first, I was too lazy to figure out how to do it, and second, I notice that in the huge number of tests that are run, Test::More begins to drag things down.

    use Sport::Analytics::NHL::Test;
    test_team_id('SJS') # pass
    test_team_id('S.J') # fail and die (usually)

 The failures are usually bad enough to force the death of the program and an update to Sport::Analytics::NHL::Errors (q.v.), but see the next section

=head1 GLOBAL VARIABLES

 The behaviour of the tests is controlled by several global variables:
 * $TEST_COUNTER - contains the number of the current test in Curr_Test field and the number of passes/fails in Test_Results.
 * $DO_NOT_DIE - when set to 1, failed test will not die.
 * $MESSAGE - the latest failure message
 * $TEST_ERRORS - accumulation of errors by type (event, player, boxscore, team)

=head1 FUNCTIONS

=over 2

=item C

Either dies with a stack trace dump, or aggregates the error messages, based on $DO_NOT_DIE
 Arguments: the death message
 Returns: void

=item C

Executes a test subroutine and sets the failure message in case of failure. Updates test counters.
 Arguments: the test subroutine and its arguments
 Returns: void

=item C

Approximately the same as Test::More::like()

=item C

Approximately the same as Test::More::is()

=item C

Approximately the same as Test::More::ok()

=item C

Approximately the same as grep {$_[0] == $_} $_[1]

=item C

For the test_* functions below the second argument is always the notification message. Sometimes third parameter may be passed. This one tests if the season is one between $FIRST_SEASON (from Sports::Analytics::NHL::Config) and $CURRENT_SEASON (from Sports::Analytics::NHL::LocalConfig)

=item C

Tests if the stage is either Regular (2) or Playoff (3)

=item C

Tests the season Id to be between 1 and 1500 (supposedly maximum number of games per reg. season)

=item C

Tests the game Id to be of the SSSSTIIII form. In case optional parameter is_nhl, tests for the NHL id SSSSTTIIII

=item C

Tests if the string is a three-letter team code, not necessarily the normalized one.

=item C

Tests if the string is a three-letter franchise code, as specified in keys of Sports::Analytics::NHL::Config::TEAMS

=item C

Tests the timestamp to be an integer (negative for pre-1970 games) number.

=item C

Tests the game date to be in YYYYMMDD format.

=item C

Check if the particular stat is measured in season being processed, stored in $THIS_SEASON

=item C

Set the stats tested for a player

=item C

Tests the correct values in assists and servedby fields

=item C

Overall sequence to test the entire boxscore

=item C

Tests the event coordinates

=item C

Tests the decision for the goaltender being one of W,L,O,T

=item C

Overall sequence to test the event

=item C

Route the particular event testing according to its type

=item C

Checks the applicability of coordinates for the event and tests them

=item C

Tests the event's description (for existence, actually)

=item C

Checks the applicability of strength setting for the event and tests it

=item C

Test the boxscore's events (loops over test_event (q.v.))

=item C

Tests the goal event

=item C

Tests the header information of the boxscore

=item C

Tests the player's name (to have a space between two words, more or less)

=item C

Tests the officials definition in the boxscore

=item C

Tests the penalty event

=item C

Tests the periods' reports from the boxscore

=item C

Tests a player entry in the team's roster

=item C

Tests valid population of the player1 event field

=item C

Tests valid population of the player2 event field

=item C

Tests the player id to be the valid 7-digit one one starting with 8

=item C

Tests the position of the player to be one of C L R F D G

=item C

Tests the event's strength to be one of EV, SH, PP, PS or XX (unknown)

=item C

Tests "header" information for a team: shots, score, coach etc.

=item C

Tests teams that played in the game

=item C

Tests the time to be of format M{1,3}:SS

=item C

Tests the boxscore after it was merged with other files (e.g. via Sport::Analytics::NHL::Merger). Test options are set according to the types of reports that have been merged ($boxscore->{sources})

=item C

Tests the events of the merged boxscore

=item C

Tests the header of the merged boxscore

=item C

Tests the teams of the merged boxscore

=item C

Approximately the same as Test::More::cmp_ok()

=item C

Tests that the normalized events have been arranged correctly

=item C

Tests the consistency between the event summary and the boxscore

=item C

Tests the consistency between the goaltender data and the event summary

=item C

Tests the consistency between the penalty minutes of the players in the boxscore and in the event summary

=item C

Tests the consistency between the goals scored in the events and the goals in the boxscore teams/players

=item C

Tests the consistency between the skater data and the event summary

=item C

Full test of the normalized boxscore

=item C

Tests the normalized boxscore events

=item C

Tests the normalized boxscore's header

=item C

Tests the normalized roster of a team

=item C

Tests the normalized boxscore's teams
